The effect of a blood pressure reduction by 10 mg extended release felodipine once daily on urinary albumin excretion (UAE) as well as the possible diabetogenic effect of felodipine was studied. A 2 X 12 week placebo-controlled double-blind crossover study was performed in 12 hypertensive non-insulin-dependent diabetic (NIDDM) patients without nephropathy on concomitant treatment with beta-blocker and/or a diuretic agent. Metabolic control as estimated by fasting plasma glucose, hemoglobin A1c and fasting plasma C-peptide was unaltered after felodipine. Blood pressure was significantly reduced by felodipine: systolic 166 +/- 26 mm Hg (placebo) v 153 +/- 26 mm Hg (felodipine) (P less than .05) and diastolic 95 +/- 7 mm Hg v 90 +/- 8 mm Hg (P less than .05). Heart rate was unchanged. There was no correlation between blood pressure and UAE, but the relative change in UAE expressed as UAE placebo/UAE felodipine was significantly correlated to the fall in systolic blood pressure (r = 0.64, P = .03) and mean blood pressure (r = 0.66, P = .02). Since microalbuminuria predicts proteinuria and reduced survival, early antihypertensive treatment may be beneficial in NIDDM as it is in IDDM. Long-term consequences on kidney function and mortality remains, however, to be elucidated.

Renal failure among elderly individuals with diabetes is a substantial clinical and public health problem. These individuals account for the majority of renal failure among people with diabetes mellitus in the United States. Although limited population-based data directly provide evidence regarding the incidence of and risk factors for ESRD, extant data suggest that blacks and Pima Indians have a markedly increased risk of ESRD compared with whites in the United States. Proteinuria and microalbuminuria appear to be extremely common in elderly individuals with NIDDM and are strongly associated with overall survival, cardiovascular morbidity and mortality, and the development of ESRD. Although randomized clinical trials are needed to test intervention strategies to reduce morbidity and mortality associated with renal disease among individuals with NIDDM, extant data suggest that management efforts directed at hypertension control and, possibly, moderate restriction of protein intake may be important therapeutic modalities for prevention of renal disease and its associated sequelae among elderly individuals with diabetes.

Vibratory and cooling detection thresholds (VDT and CDT) were determined at both the palmar aspect of the distal phalanx of the right index finger (upper limb) and the plantar aspect of the distal phalanx of the right great toe (lower limb) in 53 consecutive patients with diabetes mellitus (NIDDM), in order to analyze the frequency of the abnormality of each threshold and the relationship between each threshold and the clinical or laboratory findings. VDT in the lower limb was statistically correlated with age, duration of diabetes mellitus, and blood urea nitrogen value of each patient, but not with fasting blood glucose and hemoglobin A1C levels. VDT in the lower limb was significantly greater in the groups of patients with each of the subjective sensory disturbances, peripheral neuropathy (based on our criteria), retinopathy, and proteinuria. Forty-seven per cent of the patients showed clinically peripheral neuropathy, and the frequencies of the abnormality of VDT, CDT and VDT or CDT were 34, 26 and 45%, respectively. VDT and CDT reflect the abnormality of different populations of the peripheral nerve fibers and seem to be affected separately. The determination of both VDT and CDT is useful for the evaluation of the neuropathic state of diabetic patients.

Diabetic renal disease is a major source of morbidity and mortality in Pima Indians. Excess mortality in NIDDM occurs principally in those with proteinuria regardless of whether death is due to cardiovascular or renal disease. Diabetes duration is a strong predictor of diabetic renal disease. Additional predictors include blood pressure, severity of diabetes, and, most likely, genetic or shared environmental determinants. The incidence rate of diabetic renal disease in Pima Indians with NIDDM is similar to that reported for subjects with IDDM with equivalent durations of diabetes. These observations suggest that clinical proteinuria and renal failure may occur in patients with NIDDM just as frequently as in those with IDDM. This finding has important implications and suggests that the variations in the frequency and age of onset of NIDDM among different populations and ethnic groups may be primarily responsible for the apparent variations in the frequency of ESRD associated with diabetes in different populations. Furthermore, diabetic renal disease appears to account for virtually all of the excess mortality associated with diabetes among Pima Indians and may perhaps do so in other populations. Improved survival of persons with NIDDM, an increasing incidence of this disease, and a relatively early age of onset in many populations could lead to a dramatic increase in the incidence of ESRD in the future. On the other hand, if diabetic renal disease and its consequences could be prevented, a profound improvement in the longevity and quality of life of those afflicted with diabetes might be possible.

Many areas of information in the epidemiology of diabetic nephropathy are lacking, but multiple studies designed specifically to answer these questions are currently being conducted. In the next 5-10 years, our current understanding of the epidemiology of diabetic nephropathy may either be confirmed or discredited. In the meantime, clinicians should use the data available to make decisions about treatment and should focus on the modifiable factors of glucose and blood pressure control in both IDDM and NIDDM, especially in patients with low-level albuminuria or clinical proteinuria.

In 107 patients with non-insulin dependent diabetes(NIDDM), plasma growth hormone(GH) responses during standard arginine test (0.5 g/kg of body weight) were studied and analyzed in comparison with those in 17 normal subjects. The indices of the responsiveness of GH, peak value of GH, sum of GH values(sigma GH), area of GH curve(integral of GH), sum of GH values above fasting level(sigma delta GH) and area of GH curve above fasting level(integral of delta GH) during the test (2 hr) were calculated. Data were also analyzed with multiple regression analysis using stepwise method for variable selection. Basal level of GH was significantly higher in diabetic patients than in normal subjects (2.1 +/- 1.7 vs. 1.6 +/- 0.5 ng/ml, mean +/- SD, p less than 0.05), and sigma GH and integral of GH were also higher in diabetic patients. There was a significantly positive correlation between fasting plasma glucose(FPG) and basal level of GH (r = 0.24, n = 107, p less than 0.05), and the indices of GH responses except delta GH and GH peak value (r = 0.24 to 0.31, p less than 0.05 to 0.01). Some indices of GH responses (sigma delta GH, sigma GH, integral of delta GH and integral of GH) were significantly higher in the poor control group (patients with FPG above 180 mg/dl, n = 29) of diabetic patients than in the good control group (patients with FPG below 140 mg/dl, n = 59), or in the group with no abnormal findings of retinopathy (n = 46). During the follow-up of retinopathy for 2.5 years on the average, progression of retinopathy was found in 21 out of 107 patients. Significantly higher GH, and GH in the patients with increasing severity of retinopathy were revealed retrospectively compared to the patients without it. However, there were no significant differences in these parameters between both groups matched by FPG or severity of retinopathy. Multiple regression analysis to the basal GH level and GH responses during arginine infusion as criterion variables of various predictor variables (total 44 factors: biochemical laboratory data, indices of glucose and insulin response to oral glucose load, indices of glucose response to arginine, age, age of the onset, obese index, duration of retinopathy, neuropathy, and therapy) were performed in 86 patients using forward and backward method for variable selection. Basal plasma level of GH showed close positive association with therapy and proteinuria and negative association with age and obesity. Five of 6 indices of GH responsiveness showed significant relationship with retinopathy.(ABSTRACT TRUNCATED AT 400 WORDS)

The detection of overt albuminuria (> 300 mg/g creatinine) in the absence of azotemia was used to diagnose early nephropathy in 34 Pima Indians with NIDDM of 16 +/- 1 years duration. Differential solute clearances were performed serially to define the course of the glomerular injury over 48 months. At baseline, the GFR (107 +/- 5 ml/min), filtration fraction and sieving coefficients of relatively permeant dextrans (< 52 A) were all depressed below corresponding values in 20 normoalbuminuric Pima Indians with a similar duration of NIDDM. Over the ensuing 48 months the GFR (-34%) and filtration fraction (-13%) in the nephropathic patients declined further. The sieving coefficients of large, nearly impermeant dextrans (> 56 A radius) increased selectively and fractional clearances of albumin and IgG increased correspondingly by > 10-fold. Analysis of the findings with pore theory revealed: (1) a progressive decline in pore density and the ultrafiltration coefficient (Kf); and (2) broadening of glomerular pore-size distribution that resulted in greater prominence of large pores (> 70 A radius). We conclude that increasing loss of intrinsic ultrafiltration capacity is the predominant cause of the early and progressive decline in GFR that follows the development of nephropathy in NIDDM. We speculate that progressive impairment of barrier size-selectivity contributes to but does not fully account for the increasingly heavy proteinuria that is observed early in the course of this disorder.

There are few data on the risk factors for diabetic nephropathy in the Asian Indian population, although several studies have shown a high prevalence of the disease in this ethnic group. This study also aimed to assess the role of hyperglycaemia and hypertension in the causation and course of nephropathy in this population, which has low rates of obesity. Retrospective analysis of two groups of non-insulin dependent diabetic (NIDDM) patients, one without proteinuria (< 100 mg/day, n = 25) and the other with proteinuria (> or = 500 mg/day, n = 25), matched for age, sex, duration of diabetes and body mass index (BMI) was done to study the factors predisposing to proteinuria and also its progression during a 2 year follow-up. Logistic regression analysis showed that the factors contributory to proteinuria were initial HbA1 and initial systolic blood pressure. The average proteinuria during the follow-up was dependent on the initial and average systolic and diastolic blood pressure values. No correlation was seen between cholesterol or triglyceride values and the change in proteinuria. Creatinine clearance deteriorated in the proteinuric group and this was related to the presence of proteinuria and initial diastolic blood pressure. This study emphasizes the importance of blood pressure in the progression of diabetic nephropathy, even in people who have low BMI. Therefore, good control of blood pressure has an important role to play in the management of this condition.

Effects of 12 months of simvastatin treatment were examined in 48 NIDDM patients with total serum cholesterol levels exceeding 220 mg/dl and were compared with those in 35 nondiabetic patients with hypercholesterolemia. In the diabetic group, 5-10 mg of simvastatin given once daily at bedtime significantly lowered total cholesterol (21%). LDL cholesterol (28%), apoB (15%) and triglycerides (8%) levels. These changes were identical to those in the nondiabetic group, except for triglycerides which did not change significantly. HDL cholesterol increased significantly in the nondiabetic group but not in the diabetic group. The reductions in LDL cholesterol and apoB in hypercholesterolemic patients with NIDDM were not influenced by gender, age, glycemic control, the presence or absence of systemic hypertension, obesity and overt proteinuria. In addition, the decrease in LDL cholesterol was not affected by the number of risk factors per patient. Simvastatin did not significantly alter hemoglobin A1c or fasting plasma glucose and was well tolerated in both groups. Simvastatin produced beneficial effects on serum lipids and apolipoproteins and neutral effects on glycemic control in hypercholesterolemic patients with NIDDM, whether or not they had an additional atherosclerotic risk factor.

We studied renal function of 194 black subjects with duration of diagnosed NIDDM from 1 month to 36 years to determine the interaction of hypertension and diabetes on nephropathy. Renal function was assessed by isotopic GFR and RPF studies, and serum creatinine. One hundred seventeen of the 194 subjects had 24-hour urinary albumin excretion (AER). AER > 300 mg/24 h correlated with longer duration of NIDDM, decrease in GFR and RPF, and rise in serum Cr, and all subjects were hypertensive. AER 30 to 300 mg/24 h also correlated with a longer duration of NIDDM and 80% had hypertension. When 194 subjects were grouped according to duration of NIDDM and the presence or absence of hypertension, subjects who remained normotensive had normal renal function. In hypertensive subjects a decrease in GFR occurred with duration of NIDDM > 1 year and decrease in RPF with duration of NIDDM > 5 years. In hypertensive subjects with NIDDM > 10 years, 36% had impaired renal function (GFR < 80 ml/min/1.73 m2 or serum creatinine > 1.4 mg/dl) and 75% had microalbuminuria or clinical proteinuria. Within this group, those subjects who developed hypertension after their diagnosis of diabetes were likely to have evidence of nephropathy as compared to those subjects whose hypertension was diagnosed prior to or simultaneous with their diabetes: 17 of 20 (85%) versus 7 of 13 (54%), respectively (P = 0.05). These data provide insight into the relationship between hypertension and diabetes in the development of nephropathy in black NIDDM individuals.
